The Smithsonian Institution has unveiled five anonymous schemes for the Bezos Learning Center in Washington, D.C., and they are open for public comment until 19 September. Of the 200 million euros donated by Amazon founder Jess Bezos, 70 million has been earmarked for the renovation of the National Air and Space Museum, and the rest is for the Bezos Learning Center. The construction of the latter involves the controversial demolition of the pyramid-like glass restaurant building designed in 1976 by Gyo Obata.
